TMFEGIIAECATIQN forming part of Letters Patent No. 747,275, datedDecember 15,1903.

Application filed October 1, 1903. Serial No. 175,309. (No model.)

10 all whom it may concern:

lie it known that I, HENRY TSCHERNING, a citizen of the United States ofAmerica, rcsidinn at l reeport, in the county of Stephenson and State ofIllinois, have invented certain new and useful Improvements in Spring-Hinges, of which the following is aspecitication.

My invention relates to certain improvements in spring-hinges, having todo particularly with the form and arrangement of a spring therein, byreason of which said spring is made easy of application to and removablefrom the hinge and is held therein against movement in all undesirabledirections by its peculiar form and combination with the hold inn meansemployed in connection therewith.

The invention is illustrated in the drawings by means of four figures,of which Figure l is a face view of my improved hinge in its preferredform. Fig. 2 is an elevation. Fig. 3is a horizontal section lookingdownward upon a plane 3 3 of Fig, l, and Fig. 4 is a similar sectionlooking downward upon a plane i d ot'l ig. 1.

Referring to the drawings, a hinge A is made up of two leaves Ct at,pivoted together by means of rivets B O passing through the cars a aupon the leaf Ct and the ears a (t u pon theleaf ct. A verticalcylindrical socket c is provided at'the left-hand side of the left;vhand leaf, and a wire spring D is secured in said socket by means of avertical portion d, turns to the right below said socket to form aspring-coil cl, and extends upward from the left-hand side of said coilto the upper portion of the hinge, where it is connected by means of asmall link E with a perforated tongue a on the leaf a. The tension ofthe spring is such as to pull upon the link E and to press the coil dagainst the leaf ct. This holds the spring securely in place, and itwill be readily seen that the insertion of'the spring in its place inthe hinge may be effected very easily and readily by thrusting the part(1 of the wire into the socket a and then crowding the upper end of thespring to the right sufficiently to hook it into the link E. After beingonce put in this position the tension of the spring itself holds itagainst movement away from the leaf to, and the link E and the car (1 atthe lower end of the leaf a, both oppose lougitudinal movement of thespring in a direction opposite to that in which it was placed in thehinge.

I claim as new and desire to secure by Letters Patent In a spring-hinge,the combination with the pivoted leaves, one of which has a ngitudinalsocket at its outer edge and the other of which has an eye at its inneredge, of a spring having an arm connected with said eye, a coil on theside of said arm toward the other leaf and a second arm crossing thefirst and provided beyond the same with a portion bent to enter saidsocket, whereby the tension of the spring holds the coil against theleaf to which it is secured. v

In witness whereof I have signed the above application for LettersPatent, at Freeport, in the county of Stephenson and State of Illinois,this th day of September, A. D.. 1903.
